IMPROVEMENT IN NOZZLES- FOR HYDROCARBQN FURNACES.

Specification forming part of Letters Patent No. 165,113 l, dated July13, 1575 application filed 'Fe ruary 24, 1875.

To all whom it may concern:

Be it known that I, HENRY STAGEY, of Indianapolis, county of Marion,State of Indiana, have invented an Improved Injector and mode ofoperating the same for introducingcoal-tar or heavy oils into furnacesin the form of spray to cause combustion, of which the following is aspecification:

My invention consists in a novel means of introducing coal-tar or heavyoils into furnaces in the form of spray, the tar or oils bein gintroducedinto a pipe attached directly in front of an injector, whichis operated by steam or compressed air, whereby the oils are forceddirectly into the furnace in the form of spray to form combustiontherein. This I accomplish by the Acombination and arrangement of theseveral parts of the injector and oil-supply pipe, of which thefollowing is a description.

Figure l represents a sectional view ot' the injector, in which Brepresents the outside case, which is perforated with air-holes K, or

there may be an air-pipe attached instead of having so many airholes. Gis a .nipple screwed onto the rear end of the case B, and has a threadcut on the outside to receivel the adjusting nut or cap D, which canrevolve ou the flanged nipple E between the ang'e and nut F. Thisarrangement of adjustment may be varied.I The object is to adjust thenozzles G H so as to produce a larger or smaller space between them, andthus regulate the flow of air, and is accomplished by turning the nut orcap D so as to open or close the annular space between the nozzles H andG. A is the steam or compressed-air supply pipe, and enters the l case Bthrough the nipple E, and extends to the front end of the case B, wherethe nozzle H is screwed thereon. j

The nozzle H is conical in form, and has a conical hole, L, which tapersfrom the end of the pipe A to a small hole, J, at the end. The outsideof this nozzle conforms with the shape of the inside nozzle G, which isscrewed onto the front end of the case B, and has the discharge-pipe Ascrewed into the small end immediately in front of the nozzle G; andentering the dischargepipe A" is the coal-tar or oilsupply pipe N, thesupply of oils being properly gaged by a cock, P, placed above theentrance to the discharge-pipe A. The oils thus supplied are forced intothe furnace mixed with air and steam-or compressed air, if steam is notused-in the form of spray, and when ignited fills the furnace with asolid mass of flame.

What I claim as new, and wish to secure by Letters Patent, is

The combination, in a nozzle for burning h ydrocarbon-ols, of theperforated air-pipe B, steam-pipe A, conical nozzles H and G, wherebythe quantity of air is controlled, with the oil-supply pipe N, in frontof the combined air and steam-pipes, by which means the oil isintroduced into the furnace in the form of spray, substantially asspecified. i

In testimony whereof I have signed my name to this specilicatiou in thepresence of two subscribing witnesses.
